Two key concepts, central to understanding the basis and practice of interferometry are introduced: image formation with conventional telescopes, in particular the Fourier decomposition of images, and the nature and utility of measurements of the coherence function or mutual intensity. An exciting and promising technique for the application of remote sensing data has emerged in recent years: Interferometric SAR, also called INSAR. 71 0 obj <> endobj 0000021658 00000 n Introduction to interferometry. Some slides are adapted from: - Perley, Myers (NRAO synthesis imaging summer school). Michelson’s interferometer is based on the interference properties of light: a beam of electromagnetic waves coming from the same source (in the case of a radio telescope, from a celestial object) is divided into 2 parts on different paths and subsequently reconverted.

Because the wavelength of visible light is quite small very small changes in the optical path difference produce measurable changes in the intensity of an interference pattern. 0000001872 00000 n It covers the history, theory and future uses of interferometeric techniques. Phenomena caused by the interference of light waves can be seen all around. Two ways of understanding interferometry • Optics • Put a mask over an aperture: still works ~ fine • More holes allow more information through • Distribution of holes affects quality of image • Image quality improves as number of holes in mask increases • Physics • Radio sources emit random signals: noise but no signal 0000038024 00000 n The observables measured by an interferometer are fringe visibility and closure phase, which can then be tted by a model or used to reconstruct an image. startxref Acknowledgements ! ¾¥Þ»™ÍçµØ–—×èi8Üí—~‰î:~]ã¡yír¹Ý_ŽÛÀ«y¿?ªÏóúÑ> âàÀ¸Oòõ5®ûìï»o*:ü@Œs¼È±p\*Ô¾kÍÀÐãüÜ@Ȥ$ Ál‚¿",LMÃMª16BæÒ¯l”îE,„.ªÃÏäzý@­Ëà¡­ñüE¡ï{^‹Å‘:Á&=«ëÅ)’c5Êλª¿Èr\BŽ2’Rù«ôÔ¶®tÄÆ£“z6?óŒúí. • A sequence of frame‐by‐frame mode in the image processing.
